I Claims. (01. 139-171) I I In the drawings I have illustrated fragmentsThe invention relates generally to Jacquard box looms or to looms ofthis general, pattern operated type in which are providedmulti-compartment shuttle-boxes and box motion mechanisms '5 foraltering the positions of the boxes, and it primarily seeks to providenovel means controlled by the pattern equipment or jacquard head forindicating or selecting the desired effective box position and foractuating the box motion to attain that position.

An example of the type of loom generally referred to is disclosed in thepatent to Lookwood No. 573,276, issued December 15, 1896. It has beenthe custom, in looms of this general type to impose upon the delicatelyconstructed pattern or jacquard head mechanisms the loads incident tomanipulation of the shuttle-box position shifting mechanisms, especiallywhen the box-operating mechanism is of the type for shifting theshuttle-box bodily as shown in Figure 12 of the Lockwood patent anddistinguished from the rotary type of box, and this imposition ofoperating load is objectionable.

The invention seeks to avoid the load imposi- 5 tion above referred toand resides in the provision of a prime mover constantly reciprocatedfrom a power operated part of the loom, a plurality of individual,selective movement-transmitting elements constantly connected with theboxoperating mechanism and movable individually or in groups forbringing about the desired shuttle-box positions, and means actuatedfrom the pattern controlled devices or jacquard head for individually orcollectively selecting and connecting said elements for movement withthe prime mover.

With these and other objects in view which will more fully appear, thenature of the invention will be more clearly understood by following thedescription, the appended claims, and the several views illustrated inthe accompanying drawings.

In the drawings:

Figure 1 is a somewhat diagrammatic side elevation illustrating theinvention, a known form of 5 shuttle-box shifting mechanism beingillustrated and the frame shown in dotted line phantom.

Figure 2 is an end elevation of the parts shown in Figure 1, parts ofthe actuator members being broken away.

Figure 3 is a fragmentary detail vertical section taken on the line 3-3on Figure 1.

Figure 4 is a detail horizontal section taken on the line 4-4 on Figure1.

Figure 5 is a detail horizontal section taken on 55 the line 5-5 onFigure 1.

of known loom portions in combination with the novel elements comprisingthe invention. The loom frame is indicated at 5, and 6 designates aconstantly rotated shaft forming a part of the loom mechanism.

An eccentric l rotatable with the shaft 6 en-- gages an actuator membersecured to the lower end of a rod 8 vertically slidable in a bearing 9secured to a part of the loom frame as shown in Figures 1 and 3 of thedrawings. An actuator bar it is secured to and extends laterally fromthe rod 8 and is constantly reciprocated in a vertical direction byreason of the constant rotation of the eccentric l. The purpose of theconstantly reciprocated actuator bar will become apparent as thedescription progresses.

Two bell crank members H are pivoted side by side on. the loom frame andone has its respective ends connected in a pull cord or cable l2, andthe other in a pull cord or cable l3. The portions of the cords l2, l3connected with one adjacent set of bell crank arms are passed aboutindividual pulleys l4 and attached to individual actuator levers l5, thepulleys l4 and levers l5 being suitably supported upon bracket membersIt secured to a portion of the loom frame. A stop member l I may beprovided for limiting movement of the levers l5.

t should be understood that the control levers l5 are moved undercontrol of the pattern actuated devices or jacquard head of the loom. Inthe present illustration the levers are shown as movable upwardly forcontrol purposes, but it is to be understood that they may be placed tomove in any direction to accord with the direction of movement of theconnected elements of the pattern actuated devices or jacquard head. Inthe Lockwood disclosure, No. 573,276, corresponding control elements areshown at m and m and for the purpose of comparative illustration thesame reference characters are applied to the lever movement effectingelements connected with the levers I5.

In this particular disclosure I have illustrated 'my improved boxposition indicator or selector operatively connected with a box motionmechanism of known form and adapted for moving the shuttle-box to one oranother of four selective positions. This box motion mechanism isdisclosed generally in the patent to Lockwood, No. 573,276, issuedDecember 15, 1896, see Figure 12. It is to be understood, however, thatmy improved mechanismv is adaptable to use in combination with boxmotion mechanisms other than the particular example of structureselected for the present disclosure.

In the illustrated box motion mechanism there are included differentiallevers I8 and I9, operated by gear-cranks 20, 2 I, through rods orthrust arms 22, 23. My improved mechanism is designed to select andposition the gear-cranks 20, 2|, by movement of the levers 24, 25, uponwhich they are respectively mounted, and under control of the patterncontrolled devices or jacquard head.

To each of the two levers 24, 25, I secure an actuator member. Thesemembers are respectively designated 26 and 21 and are selectivelycontrolled, in a manner soon to be described, for individually orcollectively connecting the levers 24 and 25 to move with the actuatorbar or prime mover l0 so as to leave both levers 24, 25 down, as whenboth members 26, 21 are disengaged from the prime mover, to lift bothlevers. 24, 25, as when both' members 26 are engaged with the primemover, or to lift one lever 24 or 25 while leaving the remaining lever24 or 25 lowered, as

when one or the other only of the members 26, 21 is engaged with theprime mover. The levers 24, 25 thus position the gear-cranks 20 and 2|so that by their retaining-lever 28 (to which reciprocatory motion isintermittently imparted by the cam surface on the toothed segment 29through the medium of the connecting-rod 29 they may be put into gearwith one or the other of the toothed segments 29 or 30, by which theyare operated to move the rod I8 (which is coupled to the shuttle-boxesin the well known manner) through the medium of the rod I8 and the leverI8, their several and varied positions being indicated by dot and dashlines representing the center lines of the levers.

The selective actuator members 26, 21 are provided at their upper endswith hook portions respectively designated 3|, 32 and which are adapted,when suitably positioned, to hook over and attach the members inoperative connection with the prime mover, as indicated in Figure 2 ofthe drawings. I will now proceed to describe the elements by which themembers 26 and 21 are shifted, individually or collectively and underpattern or jacquard head control, into or out of the path of themovement of the prime mover.

A plate or table member 33 is secured upon the frame and supports a pairof individual pulleys 34 mounted in a bracket 35. The portions of thecords I2, l3 connected with the remaining adjacent set of bell crankarms are passed about the pulleys 34 and secured to individual actuatormember selecting and shifting blocks 36 apertured at 31 to permitpassage ofthe actuator members 26, 21 therethrough as shown in Figure 5of the drawings. It will be obvious that a pull on one or both cords |2,|3 will move a block or the blocks 36 to position one or both hooks 3|,32 over the prime mover, and springs 38 anchored to the plate 33 serveto return one or both blocks 36 and member or members 26, 21 to theinactive, prime mover disengaged position when one or both cables areallowed by the control devices to move. in the pull relaxing direction.

The pattern or jacquard head devices impart movement to the levers l5and through intermediate connections hereinbefore described to theblocks 36 for selecting and positioning the hooks 3|, 32 with respect tothe prime mover H]. The work of actually controlling the box motionmechanism is done by the power shaft 6 and prime mover I0 and hence thedelicate pattern or jacquard head mechanisms are relieved of the loadsincident to these operations. Either one or the other or both of thehooks 3|, 32 and actuator members 26, 21 may be connected with orremoved from the prime mover I0 for effecting the box motion mechanismadjustments hereinbefore described in detail.
